Standard and sensitive gate Thyristors (SCR)

Standard and sensitive-gate SCRs are invaluable when simple gate drive or mains voltage is the given environment of the system. They cover crowbar protection, motor control, mains network switching and a variety of energy pulse delivery systems.


ST's SCR devices allow a peak voltage up to 1200 V, a maximum current up to 50 A, with gate trigger current either well under 1 mA for sensitive types or x10 mA for standard gate versions.
They are available in SOT-23, SOT-223, TO-92, DPAK, IPAK, TO-202-3, TO-220, RD-91 and TO-P3 packages.
